Rider Profile

Best For	Suitable for newer riders thanks to clutchless direct drive, but the instant torque rewards a rider who respects strong low-end punch.
Purpose	Built for punchy, silent urban and back-road riding where instant torque and light weight make for playful, quick acceleration off the line.
Rider Fit	Its low seat height and light 162 kg mass make it very manageable for shorter or less physically strong riders.
Character	A quiet, torquey electric sportbike that trades a traditional engine note and long range for instant, linear acceleration and low maintenance.
Not Ideal For	Not ideal for riders planning long highway touring days or off-road adventures, given the limited range and street-focused chassis.

2020 Zero SR Rider Ergonomics Assessment

Your height

Inseam (optional)

Units

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 807mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Zero SR, with a relaxed knee angle of around 120 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
